i have seen couple of question posted on topic none of solution worked that's why posting again.

i using watin automate testing of website. using ie 11. have download , save file, not able click save or saveas button of download window. tried filedownloadhandler of watin didn't worked. not limited watin solutions. thing can use in c# code acceptable

filedownloadhandler filedownloadhandler = new filedownloadhandler(); browser.adddialoghandler(filedownloadhandler); browser.image(find.byalt("download.csv")).ancestor("a").clicknowait(); filedownloadhandler.waituntilfiledownloaddialogishandled(40); filedownloadhandler.waituntildownloadcompleted(200); 

watin not interact windows controls , in windows little. had same problem in handling windows controls had multiple versions of ie. ie 9.0 , higher have different file handling when compared <= ie 8.0 version. below works fine ie 9.0 , higher. please make sure proper references added (refer using's).
